STANDING-VALVE FULLER.

Application filed september 15, 1926. Serial No. 135,522.

In standing valve pullers heretofore in use, the standing valve engaging member was rigidly secured to the sleeve epending from the pump plunger, and when the plunger would bottom against the standing Valve the pins on the standing valve would 'be sheared off by said rigid member.

.An object of my invention 1s to provlde a slidable standing valve engaging member,

thereby preventing the shearing oil of the ins. p Another object is to provide a standing valve puller which occupies less space, thereby enabling the standing valve and plunger to be more .closely positioned.

' A further object is to provide a standing valve puller which will be positively disenq gaged when the depending plunger sleeve sitsdown on the valve.

Still another object-is to provide a standing valve puller from which the standing valve cannot be disengaged while withdrawing the same from thewell.

Other objects, advantages and features of 5 invention mayappear from the accompanying drawing, the subjoined detailed descr ption, the appended claims or in the operatlon of my device.

In the drawing:

Fig. 1 is a side elevation of my puller resting on the standing valve'and with parts broken away to show interior construction.

Fig. 2 is a side elevation of my puller in the engaged position.

Fig. 3 is a longitudinal sectional view of my puller in position in a pump.

Fig. 4 is a side elevation of the engaging sleeve.

Referring more particularly to the drawing:

My standing valve puller 1 depends from the pump plunger 2 and is secured thereto by a bushing 3, said bushingbeing provided with threads 4, 5 on the upper and lower end thereof respectively, which threads are adapted to accommodate either a ring seat or a screw seat, thereby enabling my puller to be applied to any of the well known types of plungers, by merely reversing the bushing as desired. That is, one end of the bushing screws into the top of the puller. While the other end screws into the plunger 2.

My standing valve puller 1 comprises a tube 6 in which a sleeve 7 is slidably mounted in the tube'6. This sleeve is held against rotation by a key 8 which enters the slot 9 in the tube 6 is notched as at 18 the side of the sleeve. A shoulder 10 adjacent the lower end of the tube 6 limits the downward movement of the sleeve 7.- The standing valve 11 is provided with a post i 12 rising therefrom, said post having horizontally extending pins 13. The sleeve 7 is provided with a pair of bayonet slots 14, 14,

wedge 17.

to fit upon the The sleeve 7 is so positioned in the tube 6 Y i that when the notch 18 rests on the wedge 17 the pins 13 will enter the bayonet slot 14. With the puller in the position shown in Fig. 1 it will be evidentthat by turning the tube 6 to the right the wedge 17 will cam the said tube upwardly, forcing the pins 13 into the locking position in the bayonet joint 14. The rotating movement of the tube 6 and the simultaneous upward movement, thereof, will properly carry the pin 13 into the bayonet joint by reason of the inclination of the entering slot 15. i 1

To hook on to the standing valve with my puller, the following method is adopted: The sucker rods are lowered until the tube 6 rests on the bar 16. At this point the rods are turned to the right until they have become slack at the surface. A few more turns to the right are then taken, after which the rods are raised retaining the twist in the same until the standing valve is picked up. To release the standing valve from the puller it is only necessary to lower the rods until the standing valve is seated. The notch 18 and wedge 17 causing the tube 6 to rotate to the proper position so that a straight, upward lift will release the standing valve. i

Having described my invention, I claim: 1. In a pump comprising a standing valve and a plunger, a post rising from said standing valve, pins extending from said post, a sleeve having a bayonet slot therein, means slidably mounting said sleeve on the plunger and meanson said standing valve co-acting with said mounting means, whereby, said pins are registered with said slot.

2. In a pump comprising a standing valve and a plunger, a post rising from said standing valve, pins extending from said post, a

sleeve having a bayonet slot therein, means slidably mounting said sleeve on the plunger, a Wedge on said standing valve and means on said mounting means, co-acting with said wedge whereby, said pins are registered With the bayonet slot.

3. In a pump comprising a standing valve and a plunger, a post rising from said standing valve, pins on said post, a tube depending from said plunger, a sleeve slidably mounted in said tube, said sleeve having a bayonet slot therein, adapted to engage said pins, a wedge block on said standing valve, said tube having a notch 'formedtherein, adapted to engage said wedge to register said pins with the bayonet .slot. 1

4. In a pump comprising a standing valve anda plunger, a tube depending from said plunger, a bushing adapted to screw into said plunger and tube, said bushing being adapted to accommodate either a ring seat or screw seat in the plunger, a post rising from said standing valve, engaging means on said post, a sleeve slidabl mounted in said tube, said sleeve having a bayonet slot there in, adapted to engage said engaging means and means on said standing valve, co-acting with said tube, whereby, said engaging means is alined with said bayonet slot.

5. In a pump comprising a standing valve and a plunger, a tube depending from said plunger, a bushing adapted to screw into said plunger and tube, said bushing beingadapted to accommodate either a ring seat or screw seat in the plunger, a post rising from said standing valve, pins extending from said post, a sleeve slidably mounted in said tube, said sleeve having a bayonet slot -therein, adapted to engage said pins, a wedge block on said standin valve, said-tube hav-' ing a notch formed t erein, adapted to engage said wedge whereby, said pinsjare valined with said bayonet slot.

6. In a pump comprising a standing valve and a plunger, engaging means on the standing valve, a sleeve having a slot therein, said' sleeve being adapted to engage said engaging means on the standing valve, means slidably mounting said sleeve on the plunger, and
